RAZOR.

Speccation of Letters Patent.

To ad whom it may concern:

Be it known that I, GEORGE M. HISKEY, of Los Angeles, in the county ofLos Angeles and State of California, have invented certain new anduseful Improvements in Razors; and I do hereby declare the following tobea full, clear, and eXact descript-ion of the invention, such as willenable others skilled in t-he art to which it appertains to make and usethe same.

The primary object of this invention is to provide an improved, simpleand highly efficient revoluble razor capable of being operated by anysuitable power; and a further object is to provide for automaticallyremoving the lather so as to avoid interfering with the free cutting ofthe blades.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings', Figure l is a view in side elevation.lFig. 2 is a vertical longitudinal sectional View, with parts omitted.Fig. is a view of the-blade support with the blades removed. Fig. 4 isan end view of the blade support. Fig. 5 is a view of one of the blades.Y

Referring to the drawings, 1 designates a revoluble shaft to whichrotation may be imparted by any suitable means and from any suitablemotor, a flexible shaft, such as shown at 2, Fig. 1. being connected tothe y outer end of shaft 1. The latter at the end to which theeXibleshaft is connected has an external screw ythread to accommodate a nut` 3between which and the shoulder formed by an external flange 4: islocated a tubular handle 5, the latter being preferably provided withinner flanges 6 for coperating with corresponding flanges lof shaft 1 toinsure perfect bearing for the handle and centrally positioning theshaft. That portion of shaft 1 projecting beyond flange 4: has a seriesof spirallyjarranged openings 7 and the eXtreme outer end of this shaftis longitudinally threaded to receive ascrew 8.

9 designates a series of blades, each of which is of approximatelyspiral formation, that is to say, for instance, it would make onecomplete turn in about ten inches of its length. Each blade is', asshown in Fig. 5, of concave-convex formation, and is detachably securedby any suitable means in a spiral-like position on. a tubular support 10which is detachably secured on the eX- tended end of shaft 1 by screw 8and disk 12. Each blade is shown as having two openings, each of thelatter being enlarged at one end, as at 12a, to accommodate headed lugsor screws 12b projecting from support 10.

Then a blade is positioned,- with the lugs projecting through theenlarged ends of the openings, it is then moved longitudinally top'osit-ion the heads of the lugs over the reduced portions of theopenings, and the several blades are held in position by means common toall of them, Anamely the disk 12 and screw 8. The blade support has aseries of spiral-like seats for the blades, four of which are preferablyemployed. These blades will, in practice, lie perfectly flat against theskin, and by reason of the spiral positioning will cut constantly, sinceone blade comes into action as another ceases to cut. In other words,the blades are constantly cutting, and by being spirally arranged theycut at the proper angle, and regardless of how the carrier is presentedto the face, the blades will cut from one end to the other. The outerends of the blades are about flush with disk 12, enabling the operatorto shave at the corners of the mouth and the edges of the hair. Betweenthe several blades are located circumferentially arranged ribs 13, andin the seat beneath the edge of each ofthe blades I provide a series ofopenings 14 which are designed to coincide with openings 7 ofthe shaft.The purpose of the coincident openings 7 and 14 is to allow lather to beautomatically removed through shaft l, by the creation of a partialvacuum, a hose 15 being conventionally shown in Fig. 1 as connectingshaft 1 with a suit-able vacuum pump, not illustrated.

In practice, after the blades have been properly secured to theirsupport and the latter has be n attached to the projecting end of shaftsuch shaft may be revolved, the operator holding the instrument by meansof the ollow handle 5. The spiral arrangement ofthe blades insures theproper andcontinuous engagement with the skin of the person beingshaved, and the circumferential ribs give to the blades all theadvantages of a safety razor. As the blade supratentedauiyza, 1912.

port is revolving the lather is removed by I claim as my invention 4 l.A razor comprising a revoluble hollow shaft, a handle therefor, saidshaft having a' series of openings therein, ablade support secured tosaid shaft and having a series of openings for coinciding with theopenings in the shaft, and a blade detachably secured to said support,Asuction being designed to be created within said shaft.

2. A razor comprising a hollow shaft having one or more openin stherein, a blade support mounted on sai one or more openingscommunicatin with the o ening or openings in the shaft, lades detachablysecured to such support, suction being designed to be created withinsaid shaft, and means for removably securin the blade support andtheblades on said s aft.

3. A razor comprising a hollow shaft having one or more openingstherein, a blade support mounted on said shaft and having one or moreopenings communicating with the opening or openings in the shaft, saidblade support having a series of spirally arranged seats extendinglongitudinally thereof, a series of spirally arranged blades extendinglongitudinally of said support and secured on said`se'ats, the edges ofsuch shaft andy having` blades presenting continuous' cutting surfacesthrou hout the length of the blade support, an means for removablysecuring the blade support and the blades on said shaft.

4. The combination with a hollow revoluble shaft, having a series ofperforations, and a relatively fixed hollow handle mounted on suchshaft, of a blade support detachably secured to such shaft and having aseries of perforations coinciding with the perforations of said shaft, aseries of spirallyarranged blades having openings, lugs eX- tendingfrom` said su port and tting in said openings for holding said blades tothe support, means carried by said shaft for holdingthe support andblades, and spaced apart circumferential ribs between said blades,suction being designed to be created within said shaft.

In testimony' whereof, I have signed this i specication'in the presenceof two subscribing witnesses.,
